List and briefly define four classes of real-time scheduling algorithms.
Answer to relevant QuestionsWhat items of information about a task might be useful in real-time scheduling? Maximum urgency first (MUF) is a real-time scheduling algorithm for periodic tasks. Each task is assigned an urgency that is defined as a combination of two fixed priorities and one dynamic priority. One of the fixed ...Briefly define the disk scheduling policies illustrated in Figure. Consider the disk system described in Problem 11.7, and assume that the disk rotates at 360 rpm. A processor reads one sector from the disk using interrupt-driven I/O, with one interrupt per byte. If it takes 2.5 μs to ...Define: B = block size R = record size P = size of block pointer F = blocking factor; expected number of records within a block Give a formula for F for the three blocking methods depicted in Figure.
